Title: Rotating wing aircraft
IPC: B64C11/34
Filed: 1964-02-20
Abstract: 992,208. Rotary wing aircraft. ROTORCRAFT S.A. (PROPRIETARY) Ltd. Feb. 20, 1964 [Feb. 26, 1963], No. 7091/64. Headings B7G and B7W. A rotary wing aircraft has a see-saw rotor (Fig. 1) each blade of which is torsionally flexible and is provided with a hinged tab 62 movable by a cam and follower 72, 70 (Fig. 3) to increase the blade incidence as a member 74, on which the cam is formed, moves outwardly under centrifugal force as the rotor speed increases. The member 74 is restrained by a spring 84, adjustable by a screw 90, and is also connected by a shaft 78 and line 96 to a lug 100 on a drive flange 26 (Fig. 6) driven from an engine which may also drive a propeller, through a clutch (not shown) and a pinion 32. The rotor is mounted on a shaft 14 fixed to a flange 34 to which the drive is transmitted through coil-springs 36. Thus, the application of power reduces the blade incidence to the zero lift position since the flange 26 precedes the flange 34, and the two flanges, and hence the blade incidence are maintained in this relative position by a pawl 38 and lug 42 which may be separated by a pilot-operated plunger 48. The aircraft may have a control arrangement as shown in Fig. 9, in which a lever 120 has a throttle cable 124 and a peg 130 co-operating with a stirrup 126 so that after a predetermined movement of the lever, cables 136, 138 and 140 are tensioned. These cables lead respectively to the plunger 48, to allow the lug and pawl to co-operate, to a wheelbrake release 141 and to a lever 154 to disengage the transmission clutch.
